f67v1 The four Seasons

[Diane]

Thomas,
I should be pleasantly surprised if the labels turned out to be in Latin.  As far as I'm aware, the Latins didn't know Crux as such in the early fifteenth century, although someone might have just thought it looked like a cross.  It isn't visible in the northern hemisphere, and classical astronomy had seen it as part of the Centaur's area of the sky.

Dante refers to "four holy stars' - and many think he'd access to information about the southern skies.

Also the equation of the golden star in the tail of Scorpius with the character of the scribe (either in the Islamic or the non-Islamic tradition) was unknown to Europe.

I've never found such an image for the three head-stars in Orion in Europe, either.

In fact, what we see in that folio is someone book-learned about the lunar mansions system, but "wrong" in terms of conventions and habits among those to whom the system was native.

Those four (astronomical) details are additions later than the originals, but I daresay made no later than the paint in Beinecke MS 408.

I've often wondered if we aren't seeing here the hand of a certain "Master Lemon of Genoa" .. but that's probably a digression, sorry.
